IMPORTANT CONSIDERATION

Diamond-machining is a generic term describing the application of one of two specific processes. Diamond-turning and diamond-flycutting are similar processes, each using a sculpted, solid diamond as the cutting tool. Diamond-turning and flycutting allow for the production of superior optical surface quality, down to the angstrom level, (254 angstroms = 1 microinch, and 1,000,000 microinches = 1 inch). These processes produce a degree of accuracy in tooling and fixturing, and in the parts produced, which is not possible when employing traditional machining methods. The tolerances, that is, the deviation from a mathematical model of the surface to be produced, are typically measured in fractions of a wavelength of light.

The machines on which the processes are performed, and the cutting tools themselves are expensive. The optics manufacturers must absorb considerable expenses in environmental controls and support equipment. Test equipment (to certify that the optic meets specs) is expensive. And let’s not forget that capable, experienced people complete the equation. So in the end, the customer must expect to participate in paying for all the benefits.

All this to say, Diamond-machining is a relatively expensive method.

THE BENEFITS OF DIAMOND-MACHINING

Ultra-Precision accuracy and “Optical” surface quality! Diamond-Turning or Diamond-Flycutting produces amazing figure accuracy and surface quality (without post-polishing) on aspheric, spherical and plano (flat) surfaces for either transmissive or reflective applications. Only these manufacturing processes provide ultra-precision dimensional toleranceing and angstrom-level surface quality. Applications are typically within the Visible or the Infrared spectral ranges.
